The sum of the two digits of a number is 16. the number formed by reversing the digits is 18 more than the original number. determine the original number. let t = the tens digit, u = the units digit, and u + t = 16. which of the following equations would complete the system? 9t - 9u = 18 9u - 9t = 18 tu = ut + 18

The tuition costs, c, for a local community college are modeled by c(h) = 250 + 200h, where h represents the number of credit hours taken. the local state university has tuition costs, s, modeled by the function s(h) = 300 + 180h. how many credit hours will a student have to take for the two tuition costs to be equal? round the answer to the nearest tenth of an hour.
